After finally re-emerging at a London film premiere on Wednesday, the Duke and Duchess of Cambridge (who hadn't made a public joint appearance since late January) turned up again at Thursday's reception for the Scott-Amundsden Centenary Race at Goldsmiths' Hall.

With just three days to go before the one-year anniversary of their historic wedding, Prince William, 29, and Kate Middleton, 30, both glowed and smiled meeting with members of the South Pole Scott Expedition group, which recreated a famous South Pole trek. The svelte Duchess wore a blue tweed Rebecca Taylor suit, an enamel brooch in the shape of a poppy, and blue pumps.

Robert Lee, a spokesman for the Legion, was grateful for William and Kate's support. "It was a huge morale boost. The fact [William is] here today with the Duchess of Cambridge is a great recognition of the contribution these Army personnel have made to the charity and a great boost to the fundraising effort," Lee said in a statement.

The royal pair have kept an extremely low profile since Prince William's return from a tour of duty in the Falklands. They hit Wednesday's premiere of African Cats (a benefit for charity Tusk Trust), where Kate was seen yucking it up with singer Mark Knopfler of the group Dire Straits, and William chatted with director (and Madonna's ex-husband) Guy Ritchie.

No word yet on exactly how the pair plan to celebrate their anniversary this Sunday.
